For years now, Scotty has rarely been maintained. However, it was so superior in, say, 2000, that it still remains popular and is widely used in even commercial, "mission-critical" applications. Perhaps its most palpable deterioration is in source and binary repositories, which seem monotonically to be falling away. CL no longer can easily find downloadable 3.0. I favor 3.0, even though Juergen calls it "alpha"; that simply reflects Juergen's high standards. For my part, I find it more useful and reliable than anything from the 2.x series.
In any case, when I need 3.0 sources, I use anonymous CVS, as Jürgen's page [L1 ] describes it (use password "anoncvs"):
cvs -d ":pserver:[email protected]:/anoncvs" login cvs -d ":pserver:[email protected]:/anoncvs" checkout scotty
